Submitted by bhupinderbs on Tue, 2007-03-06 04:40.
Here is a Function that convert NUMBERS into WORDS:
CREATE OR REPLACE FUNCTION f_words (p_amount IN Number) RETURN Varchar2 IS
/*****************************************************************************
--Author : Bhupinder Singh
--Creation Date : 05/03/2007
--Purpose : This Function returns amount in words.
--Parameters :
--1) p_amount : Only positive and negative values are allowed.
Precision can be entered upto 10 digits and only 2 scales
are allowed e.g 9999999999.99

-------"------- 05/03/2007 Added CASE statement for positive and negative
numbers.
